摘要:
An in vitro screening method for identifying insect tolerant genotypes or clones is described. The method comprises growing plantlets in an in vitro system, screening the plantlets for molecular variation of somaclones using RAPD analysis in vitro, selecting the somaclones having molecular variation, exposing the somaclones to insect larvae or nymphs and identifying the surviving somaclones.
摘要:
The present invention relates to a novel, insect tolerant, high yielding essential oil and menthol yielding mint plant named ‘Sambhav’, which is a cultivar of Mentha arvensis L.. The mint plant of the present invention has been developed as a result of planned experiments which devised a procedure for early selection of somaclonal variants at the in vitro stage of the variety of Mentha arvensis.
摘要:
The present invention provides a novel synergistic composition comprising extract obtained from the plant Albizzia lebbeck together with Bacillus thuringiensis &dgr;-endotoxin, useful in controlling lepidopteran insects, methods for the preparation of the composition and application of the insecticidal composition to standing crops.
摘要:
A formulation useful in the treatment of drug resistant bacterial infections comprising an effective amount of thymol obtained from the plant Trachyspermum ammi, mint oil containing an appropriate amount of monoterpenes obtained from a hybrid of Mentha spicata and Mentha arvensis, and conventional additives. A method for producing the formulation by mixing the above ingredients and a method for the treatment of drug resistance in a patient by administration of a therapeutically effective amount of the formulation.
摘要:
The invention provides a rapid in vitro method for selection of menthol rich mint genotypes from a large population of independent clones, said method comprising the steps of (i) raising a heterogeneous population of Mentha arvensis clones in vitro or by vegetative methods, (ii) transferring the plantlets/shoots to a basal medium, containing cytotoxic compounds in an amount sufficient to cause toxic effect in more than 95% of the clones, (iii) selecting surviving clones, their hardening in the glasshouse, transfer to field, reconfirmation of menthol tolerance through repeated in vitro assays, and (iv) multiplying selected clones and confirming genetic uniformity through RAPD analysis.

摘要:
The present invention is related to a method of producing organogenetic tissues from a plant of the genus Mentha, said method comprising the steps of culturing an explant from a plant of genus Mentha on an initiation medium in the presence of 400 to 600 lux light at a temperature of 23-27° C., with 16 hours of photoperiod, to obtain calli, transferring the calli to a basal medium comprising minerals and vitamins to ensure development of shoots, and culturing the shoots in a medium substantially free of growth hormones and containing menthol in a concentration of about 80 &mgr;g ml−1 to ensure root formation.
摘要:
This invention relates to a new and distinct mint plant of Mentha arvensis ‘Saksham’, developed through tissue culture, possessing the following combination of characters namely producing higher amount of menthol with high essential oil yield as well as herbage yield; possessing better growth and vegetative growth with high regenerability; has distinct molecular profile by random amplified polymorphic DNA (RAPD); retains the characteristics of tolerance to leaf spot, rust and powdery mildew as in the parent variety ‘Himalaya’; has light greenish leaves, pinkish white flowers like the parent plant ‘Himalaya’, this new plant is able to produce higher herbage, oil and menthol yield per unit area as compared to other existing improved varieties.
摘要:
The present invention relates a hexane bioactive fraction and obtained from the roots of an aromatic plant named Vetiveria zizanioides commonly found in India for inhibiting the growth of drug resistant bacterial infections in humans and animals; also relates to a pharmaceutical composition comprising the bioactive extract with other additives for inhibiting the growth of drug resistant bacterial infections in humans and animals and a process for the isolation of said bioactive extract
摘要:
The present invention relates to use .alpha.-arteether as a antibacterial agent, preferably for gyr mutant bacteria which are resistant to quinolone drugs and can be used as therapeutic agents for treating drug resistant bacterial infections, and also as a antifungal agent.
